The Goal
Develop an electricity-free, eco-friendly space cooling system that reduces farm waste by lowering temperature, controlling humidity, and improving airflow — keeping produce fresh for longer without a single watt of grid power.

How It Works
Solar heat creates convection currents in a draft tube, generating a low-pressure zone that draws air through a cooling chamber. The air passes through chalk candles, silica gel crystals, and a water tray for dehumidification, adsorption, and evaporative cooling — leveraging the stack effect and Le Chatelier's principle.

Awards & Recognition
Skillsets Formed
Top 3 Learnings
Coordinating prototyping is harder than most other things. More of your energy will go into logistics, people, and timing than into the actual engineering.
Thermo is a terribly cool subject!! Genuinely one of the most elegant frameworks for understanding how the physical world moves and changes.
Putting something out into the world is a rewarding process — but building it out is the most important part. The launch is just the beginning.
Mental Note
Personal reminder
You can build literally anything.
Grateful For
People and organisations who believed in this before it was anything.
Potential Improvements
Customise temperature, wind speed, and humidity settings per produce category — leafy, root vegetables, fruits.
Integration of image processing, neural networks, and cloud computing for full automation. Specialised computer vision for vegetable condition checking.
Robotic aspects for vegetable change and condition monitoring.
Partnership with Google Loon and Tata Trust for scaling.
